No structural gear for 2 of the 3 of us. I had civilian gear on other than my EMS jacket which despite not being "proper outdoor gear" is insanly warm. Thankfully I had also layered a merino wool base layer and my RAB thinsulate-y puffer jacket under that, REI expedition gloves and two layers of hats. One of my colleagues did not do so well, and was really inadequately dressed given that we had to strip down a bit to keep her warm. The 3rd person on the team wore his structural jacket and wildland helmet.
The UTV1 crew had their structural jackets on, but otherwise civilian.
